My main research interests are gamma-ray bursts (GRBs) and tidal-disruption events (TDEs). I study the central engine of GRBs, topics including: (1) the Blandford-Znajek mechanism (BZ) as the central engine of GRBs; (2) The effects of magnetic field (eg., magnetic coupling process (MC), magnetic stress in plunging region) on neutrino-dominated accretion flow (NDAF); (3) the comparison between BZ and NDAF models; (4) the GRMHD simulation (eg., HARM) for the accretion disk and jet launching in the GRB central engine. My research also cover the GRB jet acceleration, radiation and polarization.
Recently, I began to study TDE. Only a small fraction of TDE can launch relativistic jet. I am trying to understand the crucial factor behind such type (like Sw J1644+57, Sw J2058+05). I am also interested in the GR effects, disk formation, jet launching mechanism and radiation in TDE (TDE may enable us to study the whole story of disk accretion and jet production). My work on the measurements of SMBH spin in Sw J 1644+57 and Sw J2058+05 has been reported in
UNLV news, UNLV Rebel Yell, and referenced in this book. I also participated several observational proposal (VLBA, Chandra, LMT).
